Estimated Time

70 minutes

Materials Needed
  • Milk Makin' Math Activity Book for each student
  • Milk Makin' Math Answer Key
  • Large piece of paper & markers for each group

Vocabulary

accountant: a professional who keeps records of business-related financial transactions

dairy farmer: a farmer who specializes in raising dairy cattle, specifically for milk and/or cheese products

dairy nutritionist: an animal health professional who specializes in the nutritional needs of dairy cows; nutritionists recommend the best diets for cows and monitor how cows respond to their feeding program

marketing manager: advertises, promotes, and sells products to distributors, processing plants, and eventually, to the public

safety inspector: helps prevent harm to workers, property, the environment and the general public; makes sure the dairy products we consume are safe and healthy to eat; also makes sure the food we eat is free from germs and stored at the correct temperature

veterinarian: a doctor who treats animals

Background Agricultural Connections

This lesson is part of a series called, Milk Matters: Discovering Dairy. These lessons introduce students to the history, production, nutritional value and economic significance of the dairy industry. Other related lessons include:

Dairy careers require a variety of skills, including skills in science, technology, reading, writing and mathematics. This lesson features real-life math challenges that individuals working in the dairy industry face everyday. Students will make important connections between the math problems completed in school and the math skills essential to employment. Students will study the career fields of a safety inspector, marketing manager, accountant, veterinarian, and dairy nutritionist.

More background information on the dairy industry can be found here.

Engage
  1. Draw! Give students markers and a large white sheet of paper, and three minutes to brainstorm dairy-related careers. Working in groups, students draw as many images as possible representing careers found on a dairy.
  2. Encourage students to share their drawings with the entire class. Create a master list of careers on the board and brainstorm important skills these individuals need to be successful with their jobs.
  3. Discuss and emphasize how math skills are essential for all jobs, including work on a dairy.
Explore and Explain
  1. For this lesson, groups of students (determined by the teacher) will rotate between six different learning stations. Each station should be set up with one table and chairs for each student in the group. Each station will focus on a different dairy career. Students will move around the room, completing math challenges found in each student’s Milk Makin’ Math Activity Book. Set up each of the stations as follows:
    • Station 1: Dairy Nutritionist 
      Visual: Samples of hay, dairy feed components. With each sample, include a label and definition
    • Station 2: Dairy Farmer
      Visual: One or more photos showing the inside of a milking barn.
    • Station 3: Veterinarian
      Visual: A syringe with the needle removed.
    • Station 4: Accountant
      Visual: A checkbook to represent expenses and a dollar to represent profit. Using index cards, define and label each as profit or expense.
    • Station 5: Safety Inspector
      Visual: A large weather thermometer that shows temperature in degrees Fahrenheit.
    • Station 6: Marketing Manager
      Visual: Place one gallon of milk on a digital scale.
  2. Instruct students who complete stations early to illustrate the cover of their activity book.
  3. Review the answers to the problems with the entire class. Conclude the lesson with a class discussion on:
    • What are your impressions on the amount of math needed to be successful in your career?
    • Which career would you enjoy most? Why?
    • Which job is the most difficult? Why?
    • Which job is the easiest? Why?
  4. On an index card, students write down one fact they learned about one of the possible dairy careers. Students will use this “ticket” to be excused for lunch, recess or a nutrition break. 

Variations:

  • Students move around the stations in pairs. Students complete each math challenge together.
  • Students create a dairy “passport.” With each completed station, they receive a stamp to show their success.
  • Students complete a KWL chart to begin the lesson. 
Elaborate

  • Visit the Interactive Map Project website and view the Dairy Cattle Inventory map. As a class identify the highest milk producing states and discuss the factors which could contribute to the success of dairy farms such as climate, open space, etc. Identify where your state ranks in dairy cattle production and discuss the factors contributing to the statistic.

  • Invite individuals representing dairy careers to sit on a panel for the class. Students have the opportunity to learn about each of the careers by asking questions of each guest speaker.

  • Invite individuals from each dairy career to monitor activity stations.

  • Students work in groups to research each dairy career. This activity may include interviewing employees in the industry, researching online or role-playing job responsibilities.

Evaluate

After conducting the following activities, review and summarize the following key concepts:

  • There are many careers related to dairy farming.
  • Agriculture is responsible for producing the most important necessities for daily living including food, fiber, and shelter.
  • Dairy farms produce milk, but they also provide many different jobs.
